Hi all, my 2017 DL1000 needs its 22.5k service. I called up a main dealer in Chels*a and to be honest, the bloke did not seem to have much idea about what the service involved ("valves" (false, from my Suzuki manual), "tank off", "a big job") about £300-400 all-in. Didn't inspire confidence. Can anyone recommend an independent or dealer somewhere between SW London to Canary Wharf or thereabouts? How much should the service cost? Many Thanks.
